ADJUSTER FOR ELECTRIC-LAMP REFLECTOR S SPECIFICATION forming part ofLetters Patent No. 453,002, dated May 26, 1891.

Application filed January 3, 1891. $erial No. 376.571. (No model.)

To all whom it may concern.-

Be it known that I, J AMES E. HAMILTON, a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Adjusters forElectric-Lamp Reflectors, which are fully set forth in the followingspecification, reference being had to the accompanying drawings. forminga part hereof, and in which- Figure 1 shows my incandescent-lampreflector or shade-adjuster applied to a lampshade arranged to throw thelight in a lateral direction, the dotted outlines showing the originaland natural position of the shade,

Fig. 2 shows the form of clamp used on the cord at, on an enlargedscale.

Like letters refer to like parts.

The object of my invention is to produce a device which may be readilyapplied to any incandescent-lamp shade orreflector,by means of which theshade or reflector may be made to throw its light in any desireddirection, and to attain said desirable result I construct and apply mysaid new device substantially as follows, namely:

I provide a cord 0, of any suitable size and length, and secure to oneend of it a hook 6, adapted to pass over the lower edge of the reflectoror shade b, and to the opposite end of said cord I attach a clamp d, ofany suitable construction that is adapted to hold onto the pendent orconductor-cord a; but preferablyI use the construction here shown, inwhich said clamp consists of a semi-cylindrical shell f, provided withlugs near its center, which are united by pins f to a similar pair oflugs forming a part of the opposite member d (P, thus forming ahinge-joint. The cylindrical shell (1 receives and holds one end of thesaid cord 0, and by the weight thrown on said cord 0 causes the foot (1to press upon the cord a, so as to bind said clamp (1 onto the cord a atany desired point that it may be placed.

To operate my said device I hitch the hook 6 over the lower edge of theshade b and then regulate the degree of inclination to be given to theshade by sliding the said clamp (Z up or down on the cord a. This isaccomplished by pressing the part cl toward the part f, so

as to release the foot (1 from the cord a, and then raising or loweringthe said clamp (Z on the cord 0. until the reflector assumes thenecessary angle to Obtain the light in the desired direction.

lVhat I claim is- 1. The combination, with a cord, of a lamp andreflector suspended thereby, and a cord 0, extending from thesuspending-cord to the reflector and constructed to adjustably hold thereflector at the desired angle, substantially as specified.

2. The combination, with the cord, of a lamp and reflector suspendedthereby, and a cord 0, provided at one end with a clamp for adjustablysecurin g it to the suspending-cord and at the other end with a hook forengaging the edge of the reflector, substantially as specified.
